Custom Unit Flood Mixed (Made from scratch) image - Halo Wars Overhaul mod for Halo Wars: Definitive Edition
Basically a mod that changes quite alot of content it makes the flood playable increases squad sizes and more I used Slafto's play as flood mod as a base but I made most of the changes myself I did this in my spare time and debated if I should release it I decided I would there are a couple of bugs mainly with the flood I made the rebel snipers trainable and the flood can train them to this was an accident and I could fix it pretty easy but I have decided not to the AI will train the snipers and the flood ai from what i have seen will sit there and do nothing or start training snipers and flood brutes for some reason I changed the player colors so that player 1 will always be red because its my favorite color. I may make a couple balance updates/fix some bugs not sure.
Basically you can make a new squad of units using some basic scripting it's not that hard but I made a custom squad for the flood for fun I didn't bother the add a name so there called infected grunts.
